To all whom it may concern:

Be it known that I, IRA WSXYDER, of the town of Dryden, Tompkins county, New York, have iuvented an improved \Vater-Wl1eel, of which the following is a specilication.

My object is to make an eliicient wheel, and iny invention relates more particularly to the manner of doing this, as will be seen as I describe it.

Figure lis a View of my wheel, and of the fiume that leads the water to it, the flume being in section.

Figure 2 is a section of the wheel'and axle, showing the scrolls ofthe internal portion of the wheel.

A is the axle, supported hy the bearings B and B', and

C C' are two wheels, made alike in principle, but with reversed internal scrolls, having the space 1) for the water to enter each, confined by the flume E E' E" E', which is in part represented as out away, to show the tightening-flanges F l1" of the wheels.

The inouthsG G' of the wheels are larger than y the vents HH', so that the wheels, as shown, taper toward the vents.

The vents are also ent away at l 1', to the incline of the spiral partitions or. scrolls.

In lig. 2, the same letters show the saine parts; but the main design of lthis figure is to show the arrangement ef the spiral partitions or scrolls, and J is one partition, and J' the other, ofthe right-hand wheel C, and J with J show the two partitions ot' the lefthand wheel.
